Question about Ontario childcare access and relief from expenses tax credit

[taxfree2020]

Hi,

In turbo tax 2019, for Ontario childcare access and relief from expenses tax credit, it seems you have choice to only select one parent as supporting person for child or both parents are supporting person for child. I am wondering for married couple, under what circumstances, only select one parent(either father or mother) as the supporting person for the child? If do so, what kind of supporting documents should be prepared for tax audit?

Thanks,

Cindy
